Title: Improvements in or relating to light-controlled computing devices
IPC: G06G3/00
Filed: 1941-08-27
Abstract: 548,685. Calculating apparatus. BROIDO, D. Aug. 27, 1941, No. 10937. [Class 106 (i)] [Also in Group XL] A computing device controlled by radiant energy comprises a screen, table or drum subdivided into areas, each area representing by its transparency or reflective power a precomputed result, a device sensitive to radiant energy for analysing the set area, and a control member acting continuously to operate an indicator or other control member in accordance with the transparency or reflective power of the area being analysed. For solving the equation z = f (x, y) the screen is divided into areas and these are again divided into sub-areas in accordance with the functional values. In Fig. 3, the screen 1 is in the form of a drum mounted for movement in two directions by the axial movement of a shaft 5 and by its rotative movement by means of a handle 19. The two settings are indicated by pointers 17, 21 in co-operation with scales 16, 22. A lamp 7 in a casing 8 with lenses 9 passes a beam of light on to a photocell 10 connected to an amplifier 15. The amplifier is arranged to energize a solenoid 24 the core of which is attached to a cord or chain 26 passing over a pulley or sprocket 27 on a shaft 28. The cord or chain is attached at its other end to an adjustable spring 29. The shaft 28 supports a mirror 33 to reflect a beam of light from a suitable curved lamp 34 on to a result indicating scale 35. The functional values may be represented by transparent marks or perforations on an opaque screen, or by opaque marks on a transparent screen, or by reflecting marks on a non-reflecting screen or vice-versa, or by uniformly shading an area and varying the transparency between different areas. In a modification the resultant light beam may be utilized to control the operation of a follower driven from a continuous drive. The follower may form a part of a gunnery predictor or other apparatus. In this arrangement the mirror shaft 28 is coaxial with a shaft 37, Fig. 4, on which is an arm 38 carrying two photocells 39, 40. A gear 41 on the shaft 37 meshes with the gear 42 on a differential gear 43 ... 46 mounted on coaxial shafts 47, 48 as shown in Fig. 5. The shafts 47, 48 carry co-operating clutch members 51, 57 driven in opposite directions at the same speed by gears 58 and means not shown. The clutch parts 51 are connected by levers 53 to the armatures of electromagnets 55 in circuit with the photocells 39, 40. So long as the beam of light impinges on the spot 36 between the two photocells the magnets remain energized, the clutches are effective to rotate the gears 45, 46 equally in opposite direction and to maintain the gear 42 and follower 38 stationary. If the spot of light moves to one side or the other the appropriate magnet is de-energized and the follower moves accordingly. Specifications 446,338, 521,471 and 325,268 are referred to.

Abstract: 760,839. Welding by pressure. BUSSE, F. April 21, 1954, No. 11430/54. Class 83 (4). In making a resistance butt-welded seam joint between two plates &c. the plates are clamped to a support and at least one roller electrode is brought into alignment with the joint line and relative movement between the plates and roller is caused, there being a welding strip, which becomes welded to the plates between the roller and the plates. In one embodiment two plates 8, 9, Fig. 1, are abutted on an electrode bar 4 in a lower head 2 connected to one side of a transformer and are clamped by pivoted members 6 and 7 (not shown). A roller electrode 11 movable along an upper head 3 also connected to the transformer rotates on a shaft 12 in a bracket 10 and a bracket 13 abutting a stop 14 is pivoted on the shaft 12. A reel 19 of strip, two feed rolls 21, 22, and a guide 15 are mounted on the bracket 13. In operation, with the plates clamped on the head 2, strip is fed through the guide by rotating roller 21 by hand to a position beneath the roller 11. As the roller is advanced it pulls strip from the wheel and welds it to the plates as the plates are welded. In a modification a strip feed device is arranged both in front of and behind the electrode roller, the device appropriate to the direction of electrode movement being used. In a further modification the lower electrode bar is replaced by a roller electrode and strip feed device similar to that above. For welding long seams in which it is necessary to tack weld the strip and plates before effecting final seam-welding transformers 33, 34, Fig. 6, are connected to rails 35, 36 and roller electrode devices 39, 40, similar to those already described, are in contact with the rails. A support 41 for plates to be welded is slotted and the lower device 40 operates through the slot. Preferably electromagnetic clamps are used for the plates. The electrodes are traversed by screw-drive from right to left to spot-tack weld the strips and on the return traverse from left to right the final seam welds are made. A pair of electrode devices may be provided on each rail so that in one traverse the forward one may spot-weld and the latter one make the final weld. It is stated that the plates may be clamped to a reciprocating table which is moved. relatively to a stationary electrode device.

[Also in Division C7] Alkyd resins are prepared by (a) partially esterifying the reaction product of a natural or synthetic drying or semi-drying oil and an α,#- ethylenically unsaturated dicarboxylic acid with a monocyhydric cyclic alcohol, (b) esterifying the product with an excess of polyhydric alcohol to give a hydroxyl containing product and (c) esterifying the product of (b) with a polybasic acid anhydride. In step (a) the partial esterification with monohydric cyclic alcohol may be done to give a product with n mols. of anhydride groups/mole of oil and (b) with n mols. of polyhydric cyclic (n=1, 2, 3) alcohol. The step (b) may be conducted using a partial ester of a polyhydric cyclic alcohol and the polybasic acid anhydride. The oil may be the reaction product of a drying oil fatty acid and a polyol and may be modified before, during or after reaction with the α#-unsaturated acid by copolymerization with an unsaturated monomer. The monohydric cyclic alcohol may be carbo or hetero-cyclic and may be the partial ester of a polyhydric cyclic alcohol and a fatty acid. The polyhydric alcohol may be the partial ester (containing 2 hydroxyl groups) of a polyhydric cyclic alcohol and a fatty acid. The product of the invention may be further esterified with monohydric alcohols or monoepoxides and may be rendered water-soluble by treatment with NH 3  or an amine. The examples use adducts of linseed oil with maleic acid, soyabean oil with maleic acid, linseed oil and castor oil copolymerized with styrene and maleic acid and pentaerythritol with linseed oil fatty acid and maleic acid; tricyclodecane monomethanol, methyl cyclohexanol, cyclohexanol, t.-butyl cyclohexanol, benzyl alcohol; tricyclodecane dimethanol halogenated bisphenol-A, cyclohexane - 1,2 - diol, p - xylene-α,α<SP>1</SP>-diol, 1,4- cyclohexane dimethanol; phthalic anhydride, maleic anhydride, succinic anhydride, trimellitic anhydride, respectively in the steps (a), (b) and (c). In Example 15 linseed oil, dehydrated castor oil and styrene are copolymerized and then treated with maleic anhydride and esterified. In an example an eleotrolytically depositable paint is made by adding iron oxide to an aqueous solution of a neutralized resin.
